version](https://img.shields.io/npm/v/@uiw/react-baidu-map-marker.svg)](https://www.npmjs.com/package/@uiw/react-baidu-map-marker) [![Downloads](https://img.shields.io/npm/dm/@uiw/react-baidu-map-marker.svg?style=flat)](https://www.npmjs.com/package/@uiw/react-baidu-map-marker) 表示地图上一个图像标注。 ```jsx import { Marker, useMarker } from '@uiw/react-baidu-map'; // 或者单独安装使用 import Marker, { useMarker } from '@uiw/react-baidu-map-marker'; ``` 🚧 注意：需要使用到 `<Provider>`，新的封装 `Marker` 组建使用了 `Context` 来避免 `map` 对象传来传去。 ### 基本用法 ```jsx mdx:preview import React from 'react'; import { Map, Provider, Marker, APILoader } from '@uiw/react-baidu-map'; const Demo = () => { function markerRef(props) { if (props && props.marker) { console.log('marker::', props.marker, props.map, props.BMap); } } return ( <div style={{ width: '100%' }}> <APILoader akay="eYpCTECSntZmw0WyoQ7zFpCRR9cpgHFG"> <Provider> <Map
